Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
वर्षाणां पर्वतानां च यथाभेदं तथोत्तरम् तेषां मध्ये जनपदास् तानि वर्षाणि सप्त वै //
varṣāṇāṃ parvatānāṃ ca yathābhedaṃ tathottaram teṣāṃ madhye janapadās tāni varṣāṇi sapta vai //
Now, in due order, I shall describe the distinct divisions of the regions (varṣas) and the mountains; and within those divisions lie the countries (janapadas). Indeed, those regions are seven in number.
This verse is not about Pralaya; it introduces a cosmographical catalog—how regions (varṣas) and mountains are divided, and how countries (janapadas) are situated within them.
By locating janapadas within larger regional divisions, the verse frames the idea of orderly territorial organization—useful background for kingship (rulership over janapadas) even though no direct rajadharma rule is stated here.
No direct Vāstu or ritual procedure is stated; the significance is indirect—sacred geography underlies pilgrimage networks and temple siting traditions that often align with purāṇic regional and mountain classifications.
